He's a lot smaller in person and no matter how old he gets he won't really show his age much (like an elf). He does act a little more mature (in some cases, younger or exactly like a teen in others), mostly cause he had to grow up a lot faster. He's jaded, pessimistic, drinks, smokes and a few others things a kid his age probably shouldn't have done/be doing. He likes to act like an adult.
